Abstract
This video shows an exoscope-guided single-stage resection with 3-dimensional technology of a supratentorial cavernoma and a supratentorial hemangioblastoma during the same surgical procedure. The patient is a 42-yr-old man with a history of generalized tonico-clonic seizures. Contrast-enhanced magnetic resonance (MR) revealed the presence of a left frontal cavernoma and a left T1 non-enhancing hypointese temporal lesion (hemangioblastoma). The operation was carried out in the lateral position with the sole use of a 3D-exoscope (VITOM-3D, Karl Storz GmbH&Co, Tuttlingen, Germany). The operating room set-up included the surgeons standing at the head of the patients with the operating and navigator screens in the front of them and the exoscope arm entering from the left side. As recently highlighted, the 3D-exoscope carries several advantages: (1) it allows neurosurgeons to operate in a confortable and stable position; (2) it is less space-occupying in comparison to the microscope; (3) the optics and 3D-screen offer an optimal stereoscopic view in comparison to the 2D-exoscope, important for both surgical and training purposes; (4) although sharing with the endoscope, the image quality and confortable surgeon's position, there is no conflict between the surgical instruments and the scope in the surgical field. The adopted strategy enabled a complete resection of both lesions. The postoperative course was uneventful and the patient was seizure-free; the antiepileptic drugs were discontinued 3 mo after surgery. The 3D-exoscope represents a promising surgical tool, which may become part of the neurosurgical armamentarium. Nevertheless, the conceivable capability to improve neurosurgical results will have to be explored. All procedures performed in studies involving human participants were in accordance with the ethical standards of the institutional and/or national research committee and with the 1964 Helsinki declaration and its later amendments or comparable ethical standards. The patient has consented to the submission of the surgical video for submission to the journal.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
